<3 has been so overused it doesn't even mean what it looks like anymore. People use it when they want to show someone they are happy with them. When you do something for someone and they just give you a <3 it doesn't mean much.

Said to be a "heart", yet, looks nothing like a REAL heart. I've wondered for a while where they got "<3" from a real heart. But I've finally come to a conclusion, a man made it up. If you look at it, it looks like the female body, but not JUST the female body, mens two favorite parts. The top portion, "3" resembles a woman's boobs, while the bottom half, "V" resembles her vagina. Therefore when men think "love" (the meaning of heart) they think "women's body". Therefore a man made it, and the heart is perverted.
